2014 Audi A4 S Line Black Edit TDI Quat 2.0L Heavy oil · JR07 REA

This 2014 Audi A4 TDI demonstrates a stable roadworthiness trend, with the most recent MOT test on 2025-11-24 confirming no defects at 126,541 miles. The absence of advisories or recurring failures across the last four tests suggests the vehicle has been maintained consistently within legal parameters, though the single failure in 2024-11-17—despite passing the prior test just seven days earlier—indicates a minor anomaly that warrants closer scrutiny of the exact cause. The lack of structural or drivetrain advisories implies the chassis, suspension, and turbocharged diesel system have not exhibited critical wear, but the test dates clustering around November each year may reflect opportunistic servicing rather than a disciplined maintenance schedule. The mileage progression of approximately 5,400 miles annually aligns with typical usage for a vehicle of this age, though the gap between the 2024 failure and subsequent pass—just 17 days—suggests either a rushed correction or a non-critical issue addressed outside the MOT scope. No extended periods of inactivity are evident, ruling out severe neglect, but the consistent annual mileage increments also mean consumables like brakes, tyres, and suspension components have seen steady wear. The absence of mileage jumps or prolonged stasis further supports that the vehicle has not been subjected to harsh or irregular driving conditions. Given the clean MOT history, a buyer should prioritise an independent inspection of the turbocharger and intercooler—common diesel wear points—alongside the rear brake system, which may have been the source of the 2024 failure. The suspension bushes and coil springs should be checked for excessive play or corrosion, particularly around the wheel arches where rust can compromise structural integrity. Front and rear brake discs should be measured for thickness, as repeated braking cycles at this mileage can lead to uneven wear or glazing. Finally, the exhaust system should be examined for leaks or corrosion, especially near the turbocharged sections, as diesel emissions systems are prone to failure with age.
